Real options have
tangible assets or projects as underlying asset.
The different options are sequentially put in a tree structure. In a branch, an option
can only be realised if its predecessors exist. However with the capability approach,
services (capabilities) can be used anywhere, they are independent from most of
the other services (in the realisation).
The service-oriented investment will be tested in real cases.

???There ain??™t such a thing as a free lunch.??? So, the use of Web services must be paid.
Sometimes the customer cannot know how many Web services will be implicated,
because if Web services have the same intelligence as BIA, then Web services can
invoke other Web services or even BIA. In this situation we have a cascade of Web
services and/or intelligent agents. However, it would be more preferable that the
business process itself??”through its intelligent agents??”could determine which
Web service is the best suited to fulfil its need, regarding some criteria as objective
coverage, reliability, availability, and price. The cascading of Web services with the
control of the business process or at least the logging by the business process must
be considered to evaluate the QoS of the different Web services.
